Password must Be 6 and 10 alpha numeric characters?

If a website (or other password-protected something or other) tells you that you must have a password of 6 to 10 alphanumeric characters, that means that your chosen password must be at least 6, but no more than 10, characters, which can be letters or numbers. "Alphanumeric" means letters and numbers, but not punctuation or other characters. So, "pass" would be too short, "thisismyabsurdlylongpassword" would be too long, and "@#*&@$!^" would not work because it's not alphanumeric. "P4ssw0rd" would be between 6 and 10 alphanumeric characters, although you should choose something less easy to guess than that.

What is an example of a "Valid Username"?

show.php?l=0&u=1207822&id=51735&tracking_id= A valid username typically follows certain criteria set by the website or application in question. In general, a valid username: Should be unique: It should not be already taken by another user on the same platform. Should meet length requirements: Some platforms may have minimum or maximum length requirements for usernames. May have certain character restrictions: Some platforms may only allow usernames to contain letters, numbers, or certain symbols, while others may allow any character. Should not contain offensive language or violate the platform's terms of service. An example of a valid username might be "jdoe1234" or "jane. doe". However, it ultimately depends on the specific platform's requirements and restrictions.
